I've got a Sonor 3007 maple kit with an 18" bass drum and I'm trying to decide which heads to put on either the batter or resonant side. I was thinking of either using an 18' Ambassador with a felt strip, or getting an 18" Fiberskyn PS3 for the resonant side. An issue with my bass drum right now (it currently has stock Remo UT PS3 heads) is when I try to tune it up to the pitch I want for jazz, it loses all of its body, warmth, and volume, so I'm stuck with a high-pitched punchy sound when I want to get more of a 'boom'. It may be the way I'm tuning it (currently experiented with a medium batter and a combination of a medium-tight and medium-loose resonant side), but the combination I'm using don't seem to keep the warmth heard at lower tunings show at the higher range. Any suggestions?

Fiberskyns have a nice warm sound with a hint of a dampening effect and the PS3 version should do nicely for a bass head. You could also try a Coated Emperor head, and let that two ply thickness give a bit more body to the sound. Try a tight reso side and a medium to loose batter depending on how you like the feel and sustain. You will want a non-stock reso head as well, especially for a small bass drum like that if you are looking for a big sound. Ambassadors with felt, and PS3s work great.
